Start off with the following thread.

The cost of the bars/ tape/ ... is just one component.

You don't want to attempt cutting holes in your cabinets or backsplash to fit the UCL components after they have been done. The cost of those actions imo outweigh the up front price of the bars, interconnects, power supply, ...

Thanks! I met electrician today and went to lighting store near me.

He is pricing the Seagull LED.

They showed me 2700 and 3000 although the 2700 was actually halogen but they said it would be the same temperature. I preferred the warmth of the 2700 but the salesman said 3000 is better for task lighting in kitchen.
Thoughts?

He also said you can do 2700 in the glass uppers and do 3000 for task UCL but to me that wouldn't seem to work well together.

If we do LED in the recessed lights should that temperature match as well?

We are doing light yellow lower cabs with creamy white upper cabs and am trying to see what will work best. White marble countertops

Thanks for any suggestions!

Some LED strips produce more light at a higher color temp.

I think it is a design decision whether to use different color temperatures for different lighting sources. I chose to use ~ 3500k for the UCL and 2700 for the recessed cans.

If you use the Cree CR6/ CR4 recessed lights, the color temp will match if you choose 2700k.

You probably would get better bang for the dollar with alternatives to Seagull.

Our first electrician was a no show. We used him on something else a couple of yrs ago so we requested using him for our reno b/c he was less $ than the GCs guy. Well, after a week of him not calling us or the GC back we are going with the gc's guy. However, we have to start work tomorrow so we don't have much time for decision making. The lighting store many use around us has Seagull and there didn't seem to be other options. It's unfortunate we don't have the luxury of shopping around but our guy already slowed us down by a week (by not responding) and we need to move forward on electric.

So, if you chose 3500K for the UCL, I guess the 3000 can't be too bad. I was afraid it wasn't warm enough but it's hard to tell in a lighting store with so much going on around you! ughhh.

So long as the wiring is in place and positioned correctly, the lights themselves can be installed / changed at a later time.
